fatal: not a git repository

Running pod_builder init in a newly created React Native app fails with the following:

$ pod_builder init
fatal: not a git repository (or any of the parent directories): .git

No git repository found in current folder `<redacted>/AwesomeProject/ios`!

For safety, PodBuilder can be run only under an initialized git repository

Gotcha. Maybe we can add an explicit error message that this is a requirement / that this failure is expected behavior.
